ICD-10: Q76.5

Cervical rib, classified under ICD-10 code Q76.5, is a congenital condition characterized by the presence of an additional rib that arises from the cervical vertebrae, typically the seventh cervical vertebra. This condition can lead to various clinical presentations, signs, symptoms, and patient characteristics. Below is a detailed overview of these aspects.

Clinical Presentation

Cervical ribs can be asymptomatic or symptomatic, depending on their size, location, and the presence of associated anatomical variations. The clinical presentation may vary significantly among individuals.

Asymptomatic Cases

• Many individuals with cervical ribs do not exhibit any symptoms and may remain undiagnosed throughout their lives. These cases are often discovered incidentally during imaging studies for unrelated issues.

Symptomatic Cases

• In symptomatic individuals, the presence of a cervical rib can lead to complications, primarily due to compression of nearby structures, such as nerves and blood vessels. Symptoms may include:

Signs and Symptoms

Neurological Symptoms

• Nerve Compression: The cervical rib can compress the lower trunk of the brachial plexus, leading to symptoms such as:
• Pain: Often described as a sharp or burning sensation in the neck, shoulder, or arm.
• Numbness and Tingling: Patients may experience paresthesia in the upper extremities, particularly in the ulnar nerve distribution (ring and little fingers).
• Weakness: Muscle weakness in the hand or arm may occur, affecting grip strength and fine motor skills.

Vascular Symptoms

• Thoracic Outlet Syndrome: Compression of the subclavian artery or vein can lead to vascular symptoms, including:
• Coldness or Pallor: Affected limbs may feel colder than the other side.
• Swelling: Edema in the arm or hand may develop due to venous compression.
• Claudication: Patients may experience pain during exertion due to compromised blood flow.

Musculoskeletal Symptoms

• Postural Changes: Some patients may develop compensatory postures or muscle imbalances due to chronic pain or discomfort.
• Limited Range of Motion: Pain and discomfort may lead to reduced mobility in the neck and shoulder.

Patient Characteristics

Demographics

• Age: Cervical ribs are typically diagnosed in young adults, although they can be identified at any age.
• Gender: There is a slight female predominance in the occurrence of cervical ribs, although the difference is not significant.

Associated Conditions

• Congenital Anomalies: Cervical ribs may be associated with other congenital malformations, such as scoliosis or other spinal deformities.
• Genetic Factors: Some studies suggest a genetic predisposition, as cervical ribs can occur in families, indicating a potential hereditary component.

Diagnostic Evaluation

• Imaging Studies: Diagnosis is often confirmed through imaging techniques such as X-rays, CT scans, or MRIs, which can visualize the presence of the cervical rib and assess any associated complications.
